To all whom it may concern:

Be it known that I, DE WITT COMPTON VAN VALER, a citizen of the UnitedStates of America, residing in the borough of Brooklyn, county of Kings,city and State of New York, have invented certain new and usefulImprovements in Machines for Tempering and Shaping Gold Pens, of whichthe following, taken in connection with the accompanying drawings, is afull, clear, and exact specification.

My invention relates to a machine for tempering and forming pens,particularly gold pens having iridium or like points and its object isto provide a machine to take the place of hand-work, to increase theuniformity of the product and to insure the protection of the iridium orlike point during such operation.

In carrying out this invention I make use of a shaping block or anvilpreferably formed with a stepped portion, the upper step of which isshaped to conform to the shape desired to be imparted to one side of thepen point. This upper surface or step is preferably a plane surfacehaving a slight curve at and near its edge. I also provide a hammer andmeans for forcing it towards the anvil preferably forming it with atapered head having a plane lower surface, with a straight edge and acurved edge. The. straight edge may best be located to one side of theupper step before described. To protect the iridium point I prefer tolocate, in the angle of the stepped anvil, a protecting body or block Ipreferably having its upper surface below the plane of the upper steppedsurface and formed of some softer material than the anvil, preferably ofleather. I also prefer that this protecting body be of a width slightlyless than the width of the blank formed upon one end of the pen andcarrying the iridium, so that the excess portion of said blank may benicely curved by the upper steps curved surface to gradually mold intothe shank of the pen. To secure uniformity of product, I provide aregistering means, preferably a bar of lead held by springs resilientlyagainst the protection body and preferably extending above the plane ofthe upper stepped surface, so that a workman may present a blank to theanvils upper surface with the point always at uniform distance from theedge of the same.

A preferred embodiment of my invention is set forth in the followingspecification and in the accompanying drawings, in which Figure l is aside elevation of my improved apparatus. Fig. 2 is a plan of the samewith the hammer removed. Fig. 3 is a side elevation of the blank as itcomes from the apparatus, and Fig. 4, is a view of the right face of thehammer shown in Fig. 1.

On the drawings 1 is the anvil having a base 2 provided with slots 3through which pass bolts 4 to fasten it in place. The anvil 1 is formedwith two tapered sides, one terminating in the upper stepped surface 5and the other in the lower stepped surface 6. The riser 7 between thetwo stepped surfaces may form a right angle with the lower surface andthe upper part of the riser may be curved as at 8, which curve togetherwith the curve 9 of the surface 5, is secured by bolts 24, in positionabove the anvil, into which the piston stem 25 of the hammer may pass.Although I have here shown the hammer as of the hydraulic class I do notlimit myself to so operating it.

The pen blank 26, before undergoing the operation of this machine, isflat and bluntly pointed and is provided with a blank at one end ofgreater thickness, carrying the point of iridium and making a projectionthereon having a more or less pronounced heel 27. The blank carrying theiridium from its toe to its heel is preferably of greater length thanthe width of the protecting leather body. The heel thus rests upon thecurved part of the anvil, when its toe abuts against the registeringbar. The pen is held in this easily adjusted position by the workman andthe hammer caused to descend pressing firmly against the pen and shapingthe iridium point and blank from that shown in Fig. 1 to that shown inFig. 3 and tempering the pen. The leather beneath the point protects itfrom injury and from becoming broken or injured, which must be assured.The curved corner of the hammer prevents the marring of the pen shankand the resiliently held registering rod is not. allowed to harm thepoint, for it is yieldingly held in position.

Having now fully described my invention, what I claim as new herein anddesire to secure by Letters Pat-- cut, is

1. A machine for tempering and forming the end of a pen such as hereindescribed consisting of a single stepped shaping anvil, a hammeradjacent thereto above and slightly projecting over the step, the facesof the hammer and anvil being configured in accordance to the desiredshape of the pen, a registering bar free of the hammer and higher thanthe face of the anvil, said registering bar being yieldingly held towardthe anvil.

2. A inachine for tempering and forming the end of a pen such as hereindescribed consisting of a stepped, shaping anvil, a hammer adjacentthereto, the faces of the hammer and anvil being configured inaccordance to the desired shape of the pen, a point protecting bodycomposed of a substance softer than the anvil, in the angle of the stepand adapted to support the point when the hammer is upon the pen.

3. A machine for tempering and forming the end of a pen such as hereindescribed consisting of a stepped shaping anvil, a hammer adjacentthereto, the faces of the .hammer and anvil being configured inaccordance to the desired shape of the pen, a protecting body for thepen point below the plane of the block, and in the angle of the step,and adapted to support the point when the hammer is upon the pen.

4. A machine for tempering and forming the end of a pen such as hereindescribed consisting of a stepped desired shape of the pen, a protectingbody for the pen point below the plane of the anvil, and in the angle ofthe step, and a yielding bar in front of the protecting body and bearingagainst it.

5. A machine -for tempering and forming the end of a pen such as hereindescribed consisting of a stepped shaping anvil, a hammer adjacentthereto, the faces of the hammer and anvil being configured inaccordance to the desired shape of the pen, a protecting body for thepen point below the plane of the block and in the angle of the step,said body being formed of leather.

6. In a device of the kind herein specified, a supporting anvil having astepped upper surface, a curved forward ,edge to the upper step thereof,a yielding protecting body in the angle of the lower step and of lessheight than the upper step and of a width slightly less than the blankcarrying the iridium or like point to be acted upon, in combination witha hammer above said anvil.

7. In a device of the kind herein specified, a supporting anvil having astepped upper surface, a curved forward edge to the upper step thereof,a yielding protecting body in the angle of the lower step and of lessheight than the upper step and of a width slightly less than the blankcarrying the iridium or like point to be acted upon, in combination witha hammer above said anvil, and a registering bar occupying in part atleast a position slightly above the plane of said upper step.

8. In a device of the kind herein specified, a supporting anvil having astepped upper surface, a curved forward edge to the upper step thereof,a protecting body in the angle of the lower step and of less height thanthe upper step and of a width slightly less than the blank carrying theiridium or like point to be acted upon, in combination with a hammerabove said anvil, and a registering bar occupying, in part at least, aposition slightly above the plane of said upper step, and means foryieldingly holding said bar toward said step.

0. In a device of the kind herein specified, a supporting anvil having astepped upper surf: -e, a curved forward edge to the upper step thereof,a protecting body in the angle of the lower step and of less height thanthe upper step and of a width slightly less than the blank carrying theiridium or like point to be acted upon, in combination with a hammerabove said anvil. said hammer having a flat surface adjacent to the stepand a curved edge away from the step 10. In a device of the kind hereinspecified, a supporting anvil having a stepped upper surface, a curvedforward edge to the upper step thereof, a protecting body in the angleof the lower step and of less height than the upper step and of a widthslightly less than the blank carrying the iridium or like point to heacted upon. in combination with a hammer above said anvil, and aregistering bar slightly above the plane of said upper step. restinguponsaid lower step and yieldingly held toward said iI]l] t-i' step Intestimony whereof, l have signed my name to this specification in thepresence of two subscribing witnesses Witnesses C.
